A middle-aged man and a dark-haired girl on a date in the park in the gentle sunshine. A full-fledged SM training document that starts from there. "I will soon become ill if I don't train you, and my body is only for my master. Please enjoy it with my body. Please don't abandon this female masochist Maika ..." Eventually, the Menhera girl who was trained fulfilled her desire for self-destruction with hard SM and fell into a masochist so much that she couldn't help it. #養老P
